Application-mea august is, 1922. serial m'rfssas'va `To all 'inkom itmay concermf Be it known that I, CHARLES M. MANLY, a citizen of theUnited States, residing at Richmond Hill, New York,` have invented- 5certain new and useful Improvements 1n` Tires and -Demountable Rims, ofwhichthe r followingis a specicatioln My present invention entitledImprovel mentsin tires and demountable rims 7 c'o'my .10 prises animproveddemountable rim Awhich besides having the advantages yof greatercheapness and simplicity, is adapted to have -a tire applied theretovbysimplified means without' requiring the use of a press. This A rim inits preferred form' demountably fits a wheel felloe like any standard,pneumatic tire-rim. Also said rim is circumferentially divided into twolateral parts; and the bolt meansl which I provide f or holding said 2 0parts together has a novel coaction with the 30 will appear from anunderstanding of the following description read in connection with thedrawings.

In the drawings, in" which I have attempted toshowonly one of theembodiments my invention is adapted to take, this being the particular'embodiment -which at present 1 'most prefer,-Fig. 1 is a transversesectional view through my said improved tire-rim and tire; and through astandard type of wheel 40 felloefor -demountablerims, certain of the.parts such as the bolts-beingshown in elevation. Fig. 2`is a plan viewof the inner peripheral slrface cfa ragm'ent of one lateral' partof'said rim, sa d-fragment embody- ,'45 ing. a certain lug receivableinto the standard A' apart inner members v11 andouter members 12joinedby a tread portion-13, the inner transverse notch 'or recessprovided on the wheels felloe-b'and' toA prevent .circumferentialslip ofthe tire-rim thereon.' Fig. 3`

is/a cross sectional view through said fragment onthe line :Blocking inthe direction of the arrow, said cross-section being extendedbeyond thewidth `of the fragmentv half of the rim with its fiange portion.

Y Describing now'my invention with pare ticular reference to the devicesof the drawings but ,without necessarily limiting Xmy invention thereto-A is a standard wheelfelloe Yfor a standard demountable pneumatic-tirerim; B is my improved. tire-rim;

and Cfis one of the forms of tire'embodying adapted to coact with 'saidrim.

- showt innig. as@ as to vinclu-at that entire certain improvements ofmy own which is' The standard felloe A comprises the wheel'- i felloe 1,having the standard felloe-band 2 mounted thereon, the wedge-sectioned*ring or strip `3, and the aclamping plates or lu 4, held together bythe bolt means 5 exten g through the felloe. Y Y

My tire-'rim B 's adapted to. be made bya simple rolling or shapingoperation out'of, T5 vuniformly thick sheet metal `Without any of' theup-setting :and other loperations required 'tomake astandardpneumatic-tire rimA with its various juxta osed thick and thin portions.-In my' everywhere substantially uniformly thick.

.75 ished rim, the metal is The rim "B is circumferentially' dividedValong the line 6 into two preferably-duplicate,

lateralparts. iWhen these parts are together in their operativeposition, the rim maybe described as comprising a central high substantially cylindrical portion 7 with inclined portions 8 at the sidesof said central Y.portion which diverge outwardlyto the flanges.

The aforesaid cylindricalportion 7 of the rim is'received over thecyhndricalportion of the felloe-ban'd 2, .and the inclined por'-v tions8-8 coact with the inclined portion of saidfelloe-band and with thewedging ring' 3 as shown in Figure 1.

The tire shown comprises laterallyspacedvv members'being separated bythespace 14;

and each outer member being separated from theadjacent inner member b aspace'15,the

leetiv y' vforming the-baseo thertire co forming in general shape withthe space enclosed by the flanged rim space; and all of said basal ends16 being clamped togetherl in;

said space between the two parts of the rim my means of a plurality ofbolts 17 located at intervals around the wheel and passing through holesin said' vertical portions 9 of' of the tire will be minimized.

rlhe shape of the flanged rim space enables the basal portions 16of thetire to extend `well above the bolts 17 so that the bolt holes fao "them.

through said portions do not unduly weaken 18 is'an internal clampingring of any usual or preferred form adapted to com press and clamp thebasal portions 16 of the inner members 11 etween itself "and the rimwhen the tire is i place as in lFigure 1. Said basal portions of theinner members in turn clamp the basal portions of the outer members 12against the rim and adjacent flanges. l f

vIn the particular tire shown -the outer members 12 are elbow-shapedwith said elbows directed outwardly oraway from each other and with thebasal limbs of said elbows bearing against and bein buttressedeXtraradially, and eXtra-lateral y by the divergent flange portions 10thereby increasing the laterally stabilizing effect of said outermembers on the tire when in action.

, The inner members 11 which are the main load-supporting andshock-absorbing members u are increasingly thickened towards I theirupper portions at the spaces 15 by the `them ,are

lateral extension portions 19 (laterally defined by the imaginary lines19a) which bear against the inner sides of the basal limbs of the elbowshaped members 12 and through l buttressed by the divergent flangeportions '10'. 1

The more densely cross-hatched portions of the tire in the drawings aresupposed to be more highly vulcanized or made out of a firmer, lessyielding rubber material than the other parts lofthe tire.

Referring now to Figures?. and 3, 20 is a part preferably `a forging 'oftheshape in plan shown invFigure 2 and in cross section shown'in Figure3, having its base portion permanently secured by` rivets 21 totheunderside ofone of the-two' halves of the 'flanged rim 7 at the edgewhere said half of the rimv adjoins the other half. Further said forgingcomprises a cylindrical lug 22, half l of whose circular cross-sectionlies 1n a semicircular notch formed in said rim-part to re- -ceive itand the otherhalf projects laterall towards the adjacenthalf of the rimwhic i is Aalso provided withv a semicircular notch in its edge toreceive-into it said projecting half of the lug 22when the two halves ofthe rim are together.

rlhis lug 22 and the recess inthe adjoining half of the rim prevents thetwo halves of the rim from slipping circumferentially on each other.Also/said lug prevents the rim from slipping as an entirety about tliefelloe-band 2 because the upwardly or radially inwardly directed endl ofsaid lug 22 is adapted to be received into the standard transverselyextending lrecess or groove provided in the outer periphery of thestandard felloe-band 2 for locking the standard demountable rimagainst-`slip on said standard felloe, all as will be well known tothose skilled in this art.

The expressions of direction such as upper and lower and the like usedin this description and the accompanying claims refer. to the tirepositioned as shown in Figure 1 with its tread located downwardly as ifin ground contact. i

By my above described bolted together two part rim construction I amable to forcibly apply the tire to the rim' without the aid of a pressusually required for this purpose. g To assemble the tire on my rim, itis merelyl` necessary to provide oneself with some additional longerthreaded bolts than the bolts 17. These are passed through the flange'holes in one half of the rim, then through the holes in the basalportions of the tire and ring 18 will have been previously properly YVengaged with the basal port-ions of the inner members 11 as shown inFigure 1. The described screwing up of the nuts on the long threadedbolts will Gradually force -the halves of the rim together on to thebase of the tire with the basal portions 16 compressedv and clampedlaterally between the flanges of thel rim, and compressed -and clampedvertically or radially between the ring 18and therim. Thus a press isnot needed to put a tire on my rim.` Then the lon bolts are removed andreplaced, one by one, with the short .permanent bolts 17. i

For 'greater ease inthreading same through the holes in the tire, etc.,as aforesaid, the free ends of the long bolts. will preferablybe'tapered or pointed, as .indicated by the' dott-ed lines shown attheleft hand end of the bolt 17 in Fig. 1. Y

In addition to what has been shown and described, other changes andmodifications may be made in the practical embodiment of base-'sectionsbeing compressed and tightly `my Limpfvmais' which will, nevertheless',Y still be within the spirit'of the fore oing 'disf closure andwithin-the meaning an spirit of l the annexed claimsfand which as suchare and'. the rim;
